The Aggregate Expenditures Model
The Investment Multiplier. The model of Aggregate Expenditures that we are currently considering is often called a Keynesian Model because it was first formulated by British economist John Maynard Keynes in his General Theory of Employment, Interest, and Money, published in 1936—at the height of the great depression. One of the central premises of Keynesian economics is the idea of a multiplier.
